Steel magnate Leroy Schecter is combining two side-by-side units into one large apartment that will have five bedrooms, seven bathrooms, a library, a gallery area and access to some of the best building amenities in the city. The units were listed in 2010 for a smaller $55 million asking price before being pulled from the market. The new price-hiked offering includes the cost of renovation.
